Filamentous Bacteria Control and the use of Bioaugmentation at a Food Producer
2 PagesCase Study CH-417 Situation A food processing plant was experienc- ing extremely large amounts of filamen- tous bacteria (type O21N) in their aeration basin, causing excessive bulking. They also had excessive bulking in the secondary clarifier. Several factors were the cause of these problems. •Varying plant processing needs would fluctuate the F/M ratios, causing BOD loading • Excessive BOD loading caused low DO in the aeration basins •Poor oxyg
